BASEMENT 0R GELLAR PUMP.

Application lediFebruary 7, 1927. Serial No. 12665336.

In many new communities where drainage for ground water has not been atall or adequately provided for the water recurrently accumulates in thebasements or cellars of the dwellings and sometimes to such an extent,especially during thevwinter or cool months, as to extinguish thefurnaces. `To bail or pump out such water by hand 1s a la-l bol-ions anddisagreeable job. The object` ot lo the present invention is to providean l1mproved pump of simple and Veconomical construction forautomatically removing such water as fast as it 'accumulates andbeforeit reaches a level where it can work any harm'.

5 The invention is embodied in the example herein shown and described,the features of novelty being finally claimed.

In the accompanying drawing* Figure 1 is a front eevation of the appa-20 ratus according to our invention.

Fig. 2 is an edge view of the same but broken out horizontally and withparts 1n section.

Fig. 3 is a detail in section on a larger scale.

26 of the connection between the motor shaft and the impeller shaft.

Fig. 4 is a detail of an electric switch used in the construction.

In the views 5 designates a stout slab, economically of natural wood, onwhich the operating parts are mounted. 6 designates a suitable electricmotor bolted to the upper end ofthe board, the shaft 7 of such motornormally standing parallel to the face `of the board. In the presentinstance the shaft 7 of the motor is provided with a shoulder 7 restingon the upper movable ring 32 of a ball retaining member, the lower ringor race 33 of said retaining member resting upon and supported by theprojecting perforated collar 6'l of the motor cap and a bushing 6b insaid collar. At the lower end of the board is mounted the ump casing 8,it having an arm 9 pivoted y means of a single bolt 10 to a block 11that in turn is pivoted to the board by a single bolt 12. The axes ofthe bolts 10 and 12 lie in planes at right angles to each other so thatthe pum casing can have a universal movement wit respect to the board.13 designates the ump impeller suitably journaled in the caslng, theshaft 14 of said impeller extending upward through the top of the casingin line generally with the shaft of the motor 6. The shaft 14 of thepump im M'. ller is coupled to the shaft 7 of the motor y means of tube15 of rubber clamped around having screw bolts and nuts as at 18 foradjusting the pressure of the straps so as to establish sufficientVfriction to turn the impeller shaft in normal circumstances but topermit 4the turning of the motor shaft if any obstructing means, forexample7 a stickof Wood inthe 'ca-sing, should preventthe impellershaft'from turning. This slipping coupling prevents the burning of themotor coil or coils if energized and not doing work. A slug 19 ofinsulating material is inserted between adjacent ends of the two shafts.

The lower end ci the impeller casing has secured to it a suitable screen20 forming a part ofthe impeller chamber, said screen designed toprevent the access of obstructions to the impeller chamber. The pumpcasing is provided with an outlet 21 to which flexibly attached aconductor 22 for leading the pumped water to the exterior of the cellaror basement.

23 designates a float having an arm 24 pivoted at 25 in a bracket 26attached to the edge of the board near the lower portion ot' the latter;and extending upward from any one of several hole-S 27 in a fin on thearm 24 is a rod 28 connected with an arm 29 arranged to actuate anelectric circuit maker and breaker 30, in a suitable box secured in theboard near the motor, said switch beingof an ordinary snap variety, andadapted, when the float is raised by rising water, to close theoperating circuit through the cable 31 of the electric motor.

Inthe floor of the cellar or basement where the trouble referred toexists there is dug a shallow well or sump to which thev water from allparts of the floor can flow, such well being of ample dimensionshorizontally and vertically to receive the lower end of the board, thepump casing and float.

The apparatus described is placed vertically in such well or sump withthe pump and float in position to be submerged in the down position ofthe float when the water rises in the well hence the switch of the motorwill be actuated to energize the motor when the float is liftedby therising water. Such rising water also primes the pump, and the closing ofthe lswitch starts the operation of the pump impeller thereby eventuallyreducing the level ofthe water to a point where it does not flood'thefloor. When the water is thus lowered the float falls thereby stoppingthe motor. The operation is entirely automatic and loo llo

self repeating as often as is necessary to prevent overflow. i e 4Because of the alternate wetness and dryness of the whole or a` part ofthe board 5 there is some likelihood of its warping and twisting it willtherefore be observed that a feature of especial advantage of ourconstruction is that any such warping of the board is compensated for byreason of the pump case mounting and shaft connection thereby at alltimes insuring free and proper operation of the impeller notwithstandingsuch warpin". A further important feature of the construction is thatbecause the lweight of the shaft 14; is suspended or sustained by t-heball bearings at the top, pressure of such shaft is relieved at, thecasing thereby permitting free operation of the shaft at its ilnpellerend and avoiding the necessity vfor lubrication at that end.

The forms of the parts can be changed .without departing from the gistof the invention as claimed.

What we claim is:

l.V A cellar or basement pump including a board, an electric motor and apump driven thereby on said board, said pump having a supportingconnection with said board independently of the motor, said connectionpermitting a. universal movement thereof in reneeasoz spect tothe board,a slipping clutch between the motor shaft and pump impeller shaft, anelectric switch for said motor and a float adapted to actuate the motorswitch to cause the operation 0f the pump'when the pump is primed.

2. A 'cellar or basement pump including a board, an electric motor and apump driven thereby on said board, said pump ha vingasupportingconnection with said board independentlyT of the motorrsaid connectionpermit ting a universal movement thereof in respect to the board, anelectric switch for said mo`- tor and a float adapted to actnate themotor switch to cause the operation of the pump when the pump is primed.5

3f A cellar or basement pump including a support, an electric motorsecured onsaid support having a vertically arran ed shaft, a pump havinguniversally adj ustzble means connecting it with said support, a shaftfor said pump having a slipping couplingwith said motor, shaft, and anantifriction bearing supporting said motor shaft whereby said pump shaftis in suspended relation to said motor shaft.
